How does having an EIGRP feasible successor speed up convergence?
A.
EIGRP sends queries only if there is a feasible successor, which decreases the number of routers
that are involved in convergence.
B.
EIGRP sends queries only if there is not a feasible successor, which causes less control traffic to
compete with data.
C.
EIGRP immediately installs the loop-free alternative path in the RIB.
D.
EIGRP preinstalls the feasible successor in the RIB in all cases, which causes traffic to switch more
quickly.
